Frequently asked questions
How are the colours chosen?+
The image is downsampled and its pixels are recursively split by their widest colour axis (median cut), then each bucket’s average becomes a palette colour.
Why does the palette change with size?+
More colours means finer buckets, surfacing secondary tones; fewer colours merges them into the strongest hues.
Does it ignore transparent pixels?+
Yes. Nearly transparent pixels are skipped so they don’t skew the palette.
Is my image uploaded?+
No. Extraction runs on a browser canvas.
